This news article from the Hunterdon County, New Jersey, News Service provides information on New Jersey's Ground and Surface Water Standards. The standards expedite testing of drinking water wells at risk of contamination and help prospective purchasers of brownfield sites obtain and redevelop these properties. The requirements are included in the re-adoption and amendments of the New Jersey Department of Environmental Protection's (DEP's) Technical Rules, which were last updated in 1999. These rules establish the minimum requirements for investigations and cleanup work at any site in the state where a hazardous substance may have been released. The DEP requires more complete long term monitoring and reporting when cleanup work is finished, but contamination remains. In these cases, restrictions such as institutional and engineering controls are implemented to prevent any future exposure to the contamination. Institutional controls may prohibit the installation of new wells or limit construction activities.
